Description

Technical Field

[0001] The utility model relates to the technical field of paper processing equipment, in particular to a deviation-correcting indentation and folding machine. Background Technique

[0002] In industries such as printing and packaging, the folding machine is one of the indispensable important equipment. Traditional folding machines have many problems in aspects such as paper transmission, folding accuracy, and deviation-correcting ability, and cannot meet the requirements of modern industrial production for high efficiency, high precision, and high quality.

[0003] Specifically, traditional folding machines often have a relatively complex structural design, and the coordination between components is not smooth enough, resulting in problems such as paper deviation and wrinkles during the paper transmission process. In addition, traditional folding machines also have certain limitations in folding accuracy and cannot meet the requirements of high-precision folding. In terms of deviation-correcting ability, traditional folding machines often lack an effective adjustment mechanism and cannot adapt to papers of different thicknesses and materials, resulting in unstable folding quality.

[0004] To solve the above problems, a variety of new folding machines have emerged on the market. However, these folding machines still have some deficiencies in structural design, function realization, and operation convenience. For example, some folding machines have an overly complex structural design, resulting in difficult maintenance and repair; some folding machines still need to improve in terms of folding accuracy and deviation-correcting ability; and some folding machines have deficiencies in operation convenience and cannot meet the requirements of modern industrial production for high efficiency and high quality.

[0005] Therefore, developing a deviation-correcting indentation and folding machine with a simple structure, complete functions, convenient operation, and high folding accuracy has become an urgent problem to be solved in current industries such as printing and packaging. It is under such a background that the utility model proposes a new type of deviation-correcting indentation and folding machine, aiming to solve the problems existing in traditional folding machines and improve the folding efficiency and product quality.

Any one of the paper folding rollers in the paper folding roller group is connected to a push arm, and the push arm controls the folding gap of the paper folding roller group.

[0009] Further, the pushing arm includes an arm body. A connection hole is formed at the upper end of the arm body, and the lower end is connected to the first driver. The end of the paper folding roller is inserted into the connection hole.

The folding mechanism, the paper feeding mechanism, and the paper discharging mechanism are all installed between the two side seats. The driving mechanism is arranged in any one of the mounting side seats, and the pushing arm is arranged in the other mounting side seat.

[0011] Further, the paper feeding mechanism includes a driving paper feeding table.

[0015] Advantages of the present utility model:

[0016] The deviation-correcting indentation folding machine provided by the present utility model realizes automatic paper feeding, precise folding, and stable paper discharging of the paper through the coordinated work of the paper feeding mechanism, the folding mechanism, and the paper discharging mechanism, as well as the unified drive of the driving mechanism. The whole system has a high degree of automation and flexibility, can adapt to papers of different thicknesses and materials, and improves the folding efficiency and product quality. Secondly, the folding machine has an excellent deviation-correcting effect.

[0036] Working principle:

[0037] During operation, the paper is conveyed from the transmission paper table 31 of the paper feeding mechanism 3 to the guiding mechanism 32, and the guiding mechanism 32 ensures that the paper maintains the correct direction during the transmission process. Then, the paper is smoothly fed into the paper feeding roller group 21 of the folding mechanism 2 by the guiding roller assembly 33. The paper feeding roller group 21 conveys the paper to the paper folding roller group 22 at a certain speed and tension.

[0038] At the paper folding roller group 22, the paper is blocked by the fence 5 and acts on the gap between the rollers of the paper folding roller group 22 to achieve precise folding. The distance between the paper folding rollers in the paper folding roller group 22 can be adjusted by the first driver 243 pushing the push arm 24 to adapt to papers of different thicknesses and materials.

[0039] The paper after folding is sent out through the paper folding roller group 22 and enters the paper discharging mechanism 4. The table top 41 of the paper discharging mechanism 4 serves as the supporting component of the paper. The paper moves forward under the drive of the transmission wheel group 42 and the transmission belt 43. The pressing wheel assembly 44 presses the paper to ensure that the paper does not shift or wrinkle during the movement. By adjusting the height and pressure of the pressing wheel assembly 44, it can adapt to papers of different thicknesses and materials.

[0040] The entire folding process is powered by the driving mechanism 23. The driving mechanism 23 includes a plurality of driving wheels 231 and the second driver 232. The driving wheels 231 and the second driver 232 are connected by a belt, and further drive the rotation of components such as the paper feeding roller group 21, the paper folding roller group 22, the transmission paper table 31, the guiding roller assembly 33, and the transmission wheel group 42.
